The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity …

Spiral chute, also known as a spiral separator, is commonly used in iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten ore, chrome, tin ore, niobium ore, and other non-ferrous metals, rare metals and non-ferrous metals, and metal ore separation.In particular, the effect of placer mining on seashores, riversides, sandy …

This paper summarizes the experimental work undertaken to assess the RC for the beneficiation of iron ore fines. Tests performed with a spiral tailings and a screened spiral feed showed that ...

A spiral classifier is shown in Fig. 1.The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.Dense hematite particles slide toward the inner part of …

Nesans Spiral Classifier consists of an open trough with a chute provided for the input feed material. Before being fed into the spiral classifier, the dust from the screen is mixed with water and it is carried to the input chute through a slurry pump. The inlet flow is evenly distributed across the surface area of the spirals.
